Title: Clogging prevention in ink globule jetting device
Inventor: MAEDA JIYUNJI
IPC: B41J2/165
Filed: 1984-07-30
Abstract: PURPOSE:To permit preclusion of clogging at an orifice by supplying a front chamber with ink from the first orifice under the condition in which the air vent provided at a position higher than the first orifice is left open during the period of suspended operation of an ink globule jetting device. CONSTITUTION:After completion of printing operation, a valve device 17 of an ink globule jetting device 1 is changed over and a front chamber 8 is communicated with the atmosphere. If an air pump 14 is operated under this condition, the pressure of ink within the ink chamber 5 gradually increases in comparison with the pressure within the front chamber 8 and eventually, the ink starts flowing from the first orifice to the front chamber 8. The supply of ink stated above is caused by the fact that the air vent 17out which is provided at such a position higher than the orifice 7 functions as an exhaust for the front chamber 8. Thus, the orifice 7 is covered with the ink supplied without leaving any bubble within the front chamber 8. Consequently, the orifice 7 is covered with the ink as stated above and a clogging due to the main reason of drying and adhesion of dust is prevented.

Title: Optical changeover switch
Inventor: YOSHIZAWA TETSUO
IPC: G02F1/31
Filed: 1988-06-27
Abstract: PURPOSE:To obtain the high-reliability optical changeover switch by setting two polarized light beams between a polarized light demultiplexing means and a polarized light multiplexing means equal in optical path length, and controlling polarizing direction of two polarized light by the polarized light controlling means, separately. CONSTITUTION:When a voltage is not applied to both transparent electrode couples 7 and 7', a light signal from an optical fiber 1 passes through a rod lens 2 and is separated by a polarizing film 3 into a P-polarized light signal which travels straight and an S-polarized light signal which is reflected. The P-polarized light signal is reflected by a reflecting prism 5 and reflected by a polarizing film 10 to enter an optical fiber 12'. The S-polarized light signal is reflected by the reflecting prism 5 and passes through the polarizing film 10 to enter the optical fiber 12'. The light signal is therefore projected to only the fiber 12'. When the voltage is applied to both electrode couples 7 and 7', the P signal is coupled with a fiber 12 and the S signal passes through the part of the electrode 7, so the state of the S polarized light is maintained even after the passage and the light is reflected by the prism 8 and polarizing film 10 and enters a fiber 12. Consequently, the light signal from a fiber 1 is coupled with the fiber 12 and switched.

Title: Recording apparatus and reproducing apparatus
Inventor: MATSUMI CHIYOKO
IPC: G11B20/12
Filed: 1995-06-27
Abstract: PURPOSE: To record with a recording apparatus small in circuit scale, by generating a plurality of series of signals from an input signal, and letting each series have a sufficient error-correcting ability. CONSTITUTION: An input signal is converted into format for every packet by a first formatter 11. A packet of a part of the input signal is selected by a second formatter 13 and converted into format. Outputs from the second formatter 13 and first formatter 11 are subjected to error-correcting coding by an error-correcting coding device 31 independently of each other. Since an error-correcting code here uses the same generating polynominal although the code for each output has a different code length, a circuit constitution becomes almost common to an actual one. A recording signal converter 14 converts an output of the error-correcting coding device 31 into a recording signal which is recorded by a head 15 to a tape 16.

Title: Drive system for light emitting element
Inventor: YAMAGATA MATAZOU
IPC: H04B10/29
Filed: 1977-12-27
Abstract: PURPOSE:To reduce the power consumption in the system driving the light emitting element directly with the signal current, by supplying the bias current or signal current with the power supply consisting of DC-DC converter. CONSTITUTION:In the case of the drive system for the direct drive of light emitting with signal current, the current or voltage source consisting of DC-DC converter 3 is used for the power supply to the bias current. The converter 5 includes the unit in which the input is DC current or voltage and the output is DC voltage or the unit of DC level conversion. Thus, the power consumption can be a half the conventional examples. Further, the same effect can be expected by using the DC-DC converter to the circuit supplying the signal current or voltage to the semiconductor laser. Further, the circuit can be constituted so that the optical output can be constant by changing the input voltage of the converter depending on the variation in the optical output. In this case, the converter is included in the feedback loop, then the power consumption can similarly be reduced.
